Discussion Overview

The discussion centers on the relationship between pressure and the number of moles in the context of the ideal gas equation. Participants explore whether pressure is indeed proportional to the number of moles under certain conditions, referencing specific literature and questioning the interpretations of the equation.

Discussion Character

  • Debate/contested

Main Points Raised

  • One participant questions how pressure can be considered not proportional to the number of moles.
  • Another participant references Young and Freedman's textbook, suggesting that the authors do not explicitly include the relationship between moles and pressure in their discussion of the ideal gas equation.
  • A request for clarification on the textbook's content is made, indicating a need for more specific information.
  • One participant asserts that according to the ideal gas law (PV=nRT), pressure is proportional to the number of moles when other variables are held constant.

Areas of Agreement / Disagreement

Participants express differing views on the relationship between pressure and the number of moles, with some supporting the proportionality as stated in the ideal gas law, while others reference literature that may imply otherwise. The discussion remains unresolved.

Contextual Notes

There are references to specific pages in a textbook that may contain assumptions or interpretations not fully explored in the discussion. The implications of holding other variables constant are also not fully addressed.

Who says it's not?

Young and Freedman page 591-592 in the ideal gas equation section. The author does not seem to include the relationship between the number of moles and pressure.
 
For those of us who don't have the book handy... What exactly do they say?
 
But... PV=nRT... So P is proportional to n, if you keep everything else stable...
